Application filed March 2, 1911. Serial No. 511,799.

To all whom it may concern:

Be it known that I, HIRAM W. Gonnorr, a citizen of the United States,residing at Lynn in the county of Essex and Commonwealth ofMassachusetts, have invented certain Improvements in Leather-Markers, of

- which the following description, in connec- United States LettersPatent No. 509,576,

ranted to me November 28, 1893, and used or stamping leather or solesfor shoes. Heather markers of the type described in said prior patentcomprise a handle having a head fixed upon one end thereof, the headbeing rovided with a series of die blocks projecting outradiallytherefrom, and having on their end faces raised letters or numbers.Since in some uses as for example, in stamping sizes on soles for bootsand shoes, it is often desired'to mark half sizes or the like,detachable half size dies are provided, adapted to be attached to andremoved at will from the die blocks fixed on the head of the implement.In the leather markers of the type referred to it has been thoughtnecessary in order to hold these detachable dies securely against thejarring from the hammering blows of'thc implement to provide retainingdevices whlcih, as generally made, have caused the detac 'iable dies tobe diflicult of attachment and not readily removable, for example, stifisecuring springs on the detachable dies and adapted for engagementwithrecesses 01' notches in shoulered projections on the head of the markerbeing commonly employed.

It is obviously desirable that the detachable dies ma be easily andquickly attached and remove ,and accordingly it is the object of thisinvent-ion to provide in a leather marker of the type referred toretaining devices for the detachable'dies constructed to permit thesedies to be attached and removed when desired conveniently and withoutappreciable loss of time to the operator, and

- in attached yet to construct the retaining device so as to insure thatthe detachable dies will be held position against displacement the tothe jar-ring from the hammering blows of the tool. To this end,.Ipreferably chamber out the shank portions of the detachable dies andprovide therein roller clutch devices comprisin rolls or rollersactuated by springs seate in the chambers, these rollers when thedetachable dies are attached serving by their wedgin engagement with-thesides of the fixed ie blocks to hold the detachable d-ies firmly in theproper position while yielding readily to permit these dies to be freelyremoved when desired. Moreover this construction has the furtheradvantage of doing away with much of the machine work formerly necessaryon the head of the implement. It should be understood, however, that inits broad aspectmy invention is not limited to embodiment in animplement of the type referred to in connection with which it isillustrated and described, but it is equally adapted for use whereversimilar objects are to be obtained. Moreover, various modifications ofthe precise construction hereinafter described may be made within thescope of my invention.

, Referring to the appended drawings Figure 1 is a view in perspectiveof a leather marker of the type referred to showing therewith apreferred embodiment of my invention; Fig. 2 is an elevation on anenlarged scale of one of the fixed (lie blocks with a detachable dieattached to each of two opposite sides by the retaining device whichforms the subject of this invention; Fig. 3 is a detail in elevation ofone of the detachable dies, as looked at from line 3 of Fi 2.

in the implement of the drawings, 20 is a handle of a convenient shapeto enable the operator to grasp the said handle and to use the implementafter the manner of a hammer. Fixed to the handle 20 at one of its endsis a metallic head 22 carrying on its periphery and projecting outwardradially therefrom a series of die blocks 24, having on their end facesraised numbers or stamps use of the same implement.

- ting ribs upon each'of two opposite sides of each of the dies 24; theribs 26 extending lengthwise of the blocks 24 and forming grooveslongitudinally thereof.

For enabling half sizes or a number comprising two digits to be marked,a series of detachable die blocks 30 is provided, each of the dies 30having on two opposite sides of its shank portion integral flanges 32,formed as shown in Fig. 2 to embrace snugly the correspondingcooperating ribs 26 on the fixed dies 24 for attaching the dies 30 tothe dies 24 when desired, the ribs 26 serving as runners or guidewaysalong which the flanges 32 are directed for attaching the dies 30.Preferablyas shown, and as above suggested, the fixed dies 24 areadapted to have two of the dies 30 applied at the same time to oppositesides of any one of them so that a comparatively wide range of figuresor letters can be used and numerous combinations effected in theMoreover, it will be observed that the detachable dies 30 can be usedinterchangeably on any of the fixed dies 24.

' The retaining devices for the detachable dies 30 which form thesubject of fny invention comprise in a preferred embodi-E ment rolls 34disposed in recesses chambered i in the shank or body portions of thedetachable dies 30, the said rolls 34 extending at their opposite endsoutwardly through slots 36 formed in the outer walls of the die blocks30 and being confined in the recesses in the blocks 30 by disks orwashers 35 (Fig. 2). Each of these slots 36 as shown in Figs. 2 and 3extend obliquely outwardly from a point'in the outer face of the flange32. Seated against each of the rolls 34 is a spring 37, the other end ofsaid spring abutagainst the top portion of the recess formed in-block30. These springs 37 tend normally to hold the rolls 34 in their inwardand lowermost position in the slots 36. From the construction of theretaining devices it will be apparent that when one of the detachabledies 30 is .attached to a fixed die 34 by sliding the fianges-32 overthe ribs 26 to the position shown in Fig. '2',

l the roll 34 will be moved frictionally against the tension of spring37 upwardly and out wardly in slots 36' only a suflicient amount toenable the die block 30 to be easily attached as clearly shown in Fig.2.' Since however, the .sprin 37 is tendm to force roll 34 downwar lyand inwar y in the slots 36, the said roll 34 will become wedged betweenthe side of the fixed die 34 to which it is attached and the inner wallof the recess in the body portion of the detachable die 30 so as toPrevent dislodgment of die 30 by. reason 0 00 m patent may be obtainedfor the jarring blows of the implement.v The springs 37 may however, becomparatively yielding so that a relatively slight outward and upwardpull on the disks 35 will allow the operator to remove the dies 30, therolls 34 being thereby moved against the tension of the springs 37 tothe outer.

and upper limits of their movement in slots 36 for thus removing thedies 30.

In operation the workman uses the implement as he would use a hammer,striking sharp blows to force the raised marking letters or numbers intothe stock. To assist the operator in adjusting the tool for eachoperation so that the die bearing the number he wishes to be impressedupon the leather will. project vertically downward in operativeposition, a series of raised numbers positioned opposite andcorresponding to the numbers on the fixed dies 24, is usuallyv placed asshown in Fig. 1 on the head 22,

these numbers conveniently beingsin relief of their background, the

and of a color contrasting with the finish head v22.

ont face of the Having now fully described one iilustrative form inwhich my invention may'preferably be embodied, what I claim as new anddesire to secure by, Letters Patent of the United States is 1. A'leather marker having a head, a series of fixed dies projecting fromthehead, and a series of detachable dies, the said fixed dies and the saiddetachable dies being adapted to permit the detachable dies to beremovably mounted upon the said fixed dies, and the said detachable dieshaving retaining devices comprising spring pressed rolls adapted to haveyielding engagement with the said fixeddies, and provided with outwardlyprojecting enlarged ends readily accessible to the operator b means ofwhich the said rolls may be ren ered inoperative to permit thedetachable dies to be readily removed from thefixed dies.

2. The combination with a pair of dies having slidin interlockingconnection, of means norma ly operative for preventing disengagementthereoffsaid means comprising a roller clutch device contained withinthe body portion of one of said dies and having its ends extendedoutwardly beyond the said body portion to provide means by which thesaid clutch device may b'e'rendered iinoperative to permit disengagementof the Witnesses:
